The invention relates to oil cu'psof the gravity feed type and has forits object to provide within the cup an auxiliary cup having filteringmeans in the lower end 1'5 thereof and spring means for normally forcingsaid auxiliary cup upwardly for maintaining the upper marginal edge ofthe auxiliary cup in close engagement with a single washer interposedbetween the'cap. and

the oil cup casing, thereby utilizing a sin gle washer for forming aseal between the cap, cup casing and auxiliary cup.

A further object is to provide the lower flanged base of the cup with anupwardly 1 extending stem extending through the cap and having threadedon its upper end a nut, which nutforms sole means for forcing the capdownwardly into close: engagement with the washer. V

A. further object is to fiare the upper end of the auxiliary cup so thatits upper marginal edge will engage the washer when the auxiliary cup isforced upwardly by the spring.

A further object is to provide a coiled spring beneaththe auxiliary cup,and form- .ing means whereby upon removal of thecap, said auxiliary cupwill be forced upwardly to a position above the main cup where it 3 canbe easily grasped for removal.

A furtherobject is to provide the lower end of the auxiliary cup with aperforated disc or screening means a filtering material on said disc forscreening or filtering finer particles from the lubricant, an expansiblering above the filtering material and a per forated disc supported inthe ring for screeni in the coarser particles from the lubricant. JWiththe above and. other objects in View 4 the invention residesin'theecombination and arrangement of parts as hereinafter set forthshown in the drawing, described and claimed, it being understood thatchanges in the precise embodiment of the invention maybe made within thescope of what is claimed without departing from the spirit of theinvention.

In the drawing:

downwardly from the base 1 is an extension 5 adapted to be threadedintoa bearing opening or the like for discharging lubricant through thelubricant passage 6; Extending upwardly from the base 1 is an integralaxially disposed tubular member 7, in which is threaded at 8 the needlevalve stem 9. the valve end 10 of which-cooperates with the valve seat11 .forregulating the amoun'; of lubricant allowed to enter the passage6 Lubricant enters the tubular member 7 7 through the port 12 adjacentthe base 1, therefore it will be seen that the "1 o? cant by rotatingthe finger engaging member 13. The finger engaging member is helf inadjusted position by means of a spring arm 14 carried by the tubularmember 7 and frictionally engaging the periphery of the member 13. i

Disposed within the casing 4 in space l re lation thereto is anauxiliary casing 16. the upper end'of which is preferably fia'ed as at1? tea position where it is relatively close to the upper end of themain casing l so it will engage the under side of the single annularwasher 18, which is interposed be tween thei upper end of the casing 4:and the cap 19, therefore it will be seen that a single the casing t,the auxiliary cup16 and the 5 cap 19. By this construction the number ofparts are reduced to a minimum and it is only necessary to use thesingle washer 18.

Rotatably "mounted on the upperend of tabular member 7 and an the cap1951a a closure 20, which normally closes a filling opening 21 in thecap, and threaded on the tubular member 7 is a nut 21, which whentightened forces the cap 19 downwardly into close engagement with hewasher 18 for forming a leak proof connection, however it will be notedwhen disassembling the device, it will only be necessary to remove theneedle valve and the nut, and at which time the auxiliary cup 16 will beforced upwardly by the coiled spring 22 interposed between the bottom ofthe cup and the base 1, and said cup will be forced upwardly to aposition where it can be easily grasped for removal purposes.

The bottom of the auxiliary cup 16 is provided with a perforated disc23, on which is disposed a filtering material 2%, preferably felt, andwhich filtering material is held in place by an expansible ring 25,which ring also supports a perforated disc 26. The disc 26 forms meansfor screening from the oil relatively large foreign matter, and thefiltering material2l filters finer particles from the oil. It will benoted that as the oil passes through the filter in the auxiliary cup 16,it will be screened, and the oil will assume a level in the main casingl, which is formed from transparent material, there fore it will be seenthat the level of the oil in the cup may be easily ascertained, particularly as the auxiliary cup 16 is in spaced relation to the maincasing 4, thereby allowing-the lubricant to rise between the cup 16 andcasing 4. The upper end of the auxiliary casing 16 is provided with anair port 27 whereby air may pass to and from the interior of theauxiliary cup 16 for allowing the lubricant to assume a level by gravitywithout air binding.

Extending upwardly from the perforated bottom 28 is a sleeve 28 whichsurrounds the tubular member 7 and terminates adjacent the upper end ofauxiliary cup 16 and forms means for accurately guiding the auxiliarycup 16 under the influence of the expansion spring 22, as well as underthe influence of the cap 19 when forced downwardly to closed position.

From the above it will be seen that an oil cup is provided of thegravity feed type, wherein an auxiliary cup is used having filteringmeans for the oil before it enters the main cup, a single washer is usedas a sealing means between the auxiliary cup and the main cup and thecap and upon removal of the cap spring means is provided which willforce the auxiliary cup upwardly to a position where it can be easilygrasped for removal purposes for cleaning and the like, and saidauxiliary filtering cup being placed in theoil cup in spaced relationtheretoso that the height of oil in the cup may be o ved- The inventionhaving been set forth, what is claimed as new and useful is:

1. A combined oil cup and filter comprising a main casing, a filter cupwithin the main casing in spaced relation thereto and discharging intothe main casing, an annular washer carried by the upper end of the maincasing, a flared flange carried by the upper end of the filter cup andengaging said washer, spring means for forcing the filter cup intoengagement with the washer, a cap carried by the main casing, and meansfor forcing said cap into engagement with said washer.

2. A combined oil cup and filter comprising a main casing, a filter cupin the main casing in spaced relation thereto, an axially disposedextension carried by the main casing and extending upwardly through thefilter cup, a valve in said extension controlling the fiow from the maincasing to a dis charge port, a coiled spring surrounding the extensionand interposed between the main casing and the filter cup, .a capcarried by the upper end of the main casing, a single washer interposedbetween said cap and the upper ends of said casing and the filter cup, anut threaded on the extension, said nut cooperating with the cap wherebyit is forced downwardly into engagement with the washer.

8. A combined oil cup and filter comprising a main casing, a filter cupin the main casing in spaced relation thereto, straining means carriedby the filter cup and through which oil passes to the main casing, anextension carried by the main casing and extending axially through thefilter cup and on which the filter cup is axially mounted, a coiledspring surrounding the extension and interposed between the main casingand filter cup and normally forcing the same upwardly, a cap carried bythe main casing, a single washer interposed between the cap and theupper ends of the main casing and the filter cup, and a nut threaded onthe extension and cooperating with the cap for forcing the samedownwardly into engagement with the main casing, said coiled springforming means for maintaining the upper end of the filter cup inengagement with the washer.

4.
